Looking at the early benchmarks and reviews its easy to see these cards perform about as well as to be expected. That is to say there aren't any major surprises one way or the other. They were built to fill a gap in NVIDIA's line-up and compete with some of the lower cost options from AMD and they seem to do that fairly well. This is by no means a bad thing, it simply means that this is just an everyday product launch.
